Documentation says https://developers.cloudflare.com/images/cloudflare-images/transform/flexible-variants/ that there is ability to set Flexible variants options inside Workers with cf object (inside fetch() method I guess)
My questions are:
Is that possible to use this feature for images that uploaded to Cloudflare Images?
If it’s possible, how to use it exactly?
I’ve tried to create a Worker to apply some transformations (for example, 180 degree rotation) on images that are stored at Cloudflare Images
I assumed the Worker code should look like this (hardcoded for brevity, Flexible variants feature is enabled):
export default {
async fetch(request, env, ctx) {
const account_hash = "MY_ACCOUNT_HASH"
const imageURL = "https://imagedelivery.net/" + account_hash + "/7933cea0-4e74-4c69-9283-36af7358fd00/banner";
const imageRequest = new Request(imageURL, {
headers: request.headers
})
let options = { cf: { image: {} } }
options.cf.image.rotate = 180
return fetch(imageRequest, options)
},
};
But there’s a catch – the Image Delivery URL must contain a VARIANT_NAME parameter
So my worker returns an image variant provided by fetch() url, without extra transformations
Am I missing something?
Thank you
